Soil, sodium-based montmorillonite, Sodium/Calcium base montmorillonite and magnesium-based montmorillonite, however for montmorillonite application presently, there are added value compared with
Low problem.Ferrochrome slag is the pyrometallurgical smelting generated chromium residue of when containing ferrochrome, mainly mineral hot furnace method smelting high carbon
It is generated when ferrochrome, main chemical compositions SiO2、Fe2O3、Al2O3、CaO、MgO、Cr2O3、SO3、P2O5Deng wherein Al2O3With
The content of MgO is higher, and a large amount of ferrochrome slags do not only take up valuable soil based on outdoor stockpiling at present, but also can be to ring around
Border and underground water pollute.Therefore, how extensive and high added value using montmorillonite and ferrochrome slag, realize that environment subtracts
Negative, reducing enterprise cost purpose, is a problem in the urgent need to address.Rubber is widely used as a kind of polymer material
It lives closely bound up field in vehicular traffic tire, adhesive tape, sebific duct, waterproof material etc. and people.In rubber system for processed
Cheng Zhong needs to be added reinforced filling not only to improve the mechanical property of rubber, processing performance and filling increase-volume；And it needs to be added
Fire-retardant filler is to improve the combustibility of rubber.Reinforced filling is mainly carbon black or white carbon black at present, and production technology is many and diverse, right
The energy and consumed resource are big, and leading to market price is 6000~8000 yuan/ton；Fire-retardant filler be mainly halogen based flame retardant or
Inorganic based flame retardant, wherein halogen fire retardant effect is good, but toxic gas is discharged during fire-retardant, leads to people and ring
Border causes damages, and inorganic amount of flame-retardant agent is big, will affect the mechanical property of material.In face of the above problem, montmorillonite is utilized
MgO, the Al contained in the special effects and montmorillonite and ferrochrome slag that nano-scale has2O3, research and development are with fire-retardant reinforcement
The compounded rubber filler of performance realizes that resource high added value recycles and solid waste resource circulation utilization, promotion rubber system conduct
Industry cost declining.
Summary of the invention
Reinforced filling price is high and performance is single in order to solve in existing rubber industry, and fire-retardant filler does not have reinforcing
Can, montmorillonite-ferrochrome slag is directly added into rubber and easily reunites, montmorillonite-inorganic interface of ferrochrome slag and rubber bios
The compatibility in face is poor and montmorillonite and ferrochrome slag are using the low problem of added value, the present invention provides one kind have it is fire-retardant
The montmorillonite of reinforcing property-ferrochrome slag compounded rubber filler, to solve problem above.
The present invention is achieved by the following technical programs.
The present invention provides a kind of montmorillonite with fire-retardant reinforcing property-ferrochrome slag compounded rubber filler, the montmorillonites-
Ferrochrome slag compounded rubber filler is formulated as follows by weight percentage:

Row 6~10h of mixing, obtains montmorillonite-ferrochrome slag compounded rubber filler.
The principles of science of the invention:
On the one hand, intercalation processing is carried out to montmorillonite using cetyl trimethylammonium bromide, is covered to be conducive to improve
The lipophilicity between the interlamellar spacing rate and specific surface area and montmorillonite layer of soil is taken off, to reach enhancing montmorillonite to carbon black or white
The adsorption capacity of carbon black realizes the effect to reinforcing rubber performance.
On the other hand, the montmorillonite with good lamellar structure will cause moisture pick-up properties with having the ferrochrome slag of abundant structure
Enhancing leads to the generation of montmorillonite-ferrochrome slag agglomeration, aggravates montmorillonite-ferrochrome slag dispersibility in rubber and is deteriorated, so
Using Silane coupling agent KH550-stearic acid mixed liquor, acetone mixture to good lamellar structure montmorillonite with have it is rich
The ferrochrome slag of rich structure is modified processing, not only can solve montmorillonite-ferrochrome slag problem easy to reunite, but also can be into one
Step improves montmorillonite-ferrochrome slag and rubber compatibility, further achievees the effect that reinforcing rubber performance.
In addition, containing a large amount of Al in montmorillonite and ferrochrome slag2O3With MgO, wherein Al2O3It is the compound of high rigidity, melts
Point is 2054 DEG C, and boiling point is 2980 DEG C；MgO is typical alkaline earth oxide, and fusing point is 2852 DEG C, and boiling point is 3600 DEG C.
Therefore Al2O3It is good refractory material with MgO, a large amount of Al will be contained2O3Rubber is added in montmorillonite-ferrochrome slag with MgO
In, the flame retardant property of rubber can be greatly improved, is achieved the effect that rubber flame-retarded.
Compared with prior art, the present invention has following technical effect that
1, the present invention solves reinforced filling price height in existing rubber industry and performance is single, and fire-retardant filler, which does not have, to be mended
Epistasis energy, montmorillonite-ferrochrome slag are directly added into rubber and easily reunite, and montmorillonite-inorganic interface of ferrochrome slag has with rubber
The compatibility at machine interface is poor and montmorillonite and ferrochrome slag utilize the low problem of added value.
2, the present invention is fire-retardant reinforced rubber filler using montmorillonite-ferrochrome slag, and realizes resource high added value and follow
Ring utilize with solid waste resource circulation utilization, to reduce rubber product industry cost be of great significance, meet when prosthomere recycle pass through
The industry development requirement of Ji.
